Alright, this is Rusty, and I’m looking at the outlook for Jaconé.
First thing you need to know – the water temp here is sitting right around average for this time of year, so nothing weird going on with that.
We’ve got a bit of a slow start to the period. Thursday is a write-off – messy, cross-onshore winds and the swell is just not cooperating. We’re looking at a pretty choppy, poor surf day, so don’t even bother.
The first real glimmer of hope comes on Friday morning, July 10th. The wind swings offshore from the NE, light breeze, and we get a clean 3ft SE swell. The period is a long 14 seconds, which is proper groundswell. That long period means the waves will have some real shape and energy, but at a beach break it can sometimes make things a bit straight. Still, with offshore wind and clean conditions, it’s worth a look. The combined energy is moderate (468).
The next standout is Sunday, July 12th. The morning session is clean again with a 3ft SE swell and offshore NE wind, but the real gem is the Sunday afternoon. We get some clouds, a light breeze, and a cross-offshore wind with a 4ft S swell, 11-second period. The combined energy jumps to moderate (545) and the conditions are described as clean. This is a solid window for a fun surf.
Now, listen up, because Monday afternoon, July 13th is the best of the first week. The wind goes glassy, dead calm. The swell builds to 5ft from the S, with an 11-second period. The combined energy is strong (708). This is the kind of afternoon where you’re just floating out there, no wind, and the waves are pumping. It’s not too big for a decent intermediate, but it’s got enough push to be fun.
Tuesday, July 14th is a washout. Strong onshore winds and a lumpy 5ft – 6ft swell. That’s a hard pass.
Wednesday morning, July 15th is another glassy session. The wind is dead calm from the N, and we’ve got a 5ft SSE swell. This is good, clean surf, but the period is 10 seconds, so it’s a bit more of a wind-swell vibe. The combined energy is strong (562).
Thursday morning, July 16th is a solid pick. Offshore NE wind at 9 mph, a 5ft SE swell, and good energy. It’s a clean, fun morning.
The second week gets a bit more mixed. We see a pattern of mornings with offshore NE winds and clean 3ft to 4ft swells, but the periods drop to 7 or 8 seconds – short-period wind swell. That’s weaker, less punchy surf. The afternoon winds come in from the E or ESE, so it’s not as clean.
Monday morning, July 20th is a bit of a spike. The swell jumps to 6ft from the ENE, with a 7-second period. Combined energy is strong (551) and the wind is offshore and light. That’s a lot of water moving fast, but the short period means it’ll be a bit walled up and chaotic. This one is for experienced surfers only.
The rest of the second week is a mixed bag of small, clean mornings and afternoons that are either poor or just ordinary. There’s nothing truly standout after the first week, but there are still some fun, rideable mornings if you’re keen.
Bottom line: The best windows are Sunday afternoon, July 12th and Monday afternoon, July 13th. That Monday afternoon with the glassy conditions and 5ft swell is the pick of the whole 16 days.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
